The 'entiou consis s in reinlincing the sewer coustructiani both transversely and under a large longitmllnally,

With these objects in View, the invention consists in the arrangement, combination and construction of parts hereinafter ilescribed anal more particularly pointed out 1n the claims, it lasingunderstood that .l. do not intend to hunt myself to the details oi construction of the different parts.

The invention is illustrated in the accompanying rlmwuigs in which:

Figure 1 shows a cross sectional view of designed. to he used. viewof the modifications necessary in the structure shown in Fig. l the use of my reinforcing members with one of those Ill0ll1- hers in place. Fig. 3 is a Section on. line mw of Fig 2 and shows the (:liz-zuucling necessary for the reception of the reinforc ing elemeuta Fig. l is a cross sectional view and shows my method, of transverse rein-- foroementr 5 shows (llagrammatically the location of the various reinforcing elements.

In the (lrawingstlie numeral. 1 indicates an. outer block used in sewer or conduit coustructions provided. with a recess 2 in its under face.

3 indicates lining plates used for tying the blocks 1 together. videcl with longitudinal edge ribs l that are adapted to enter the recess and be retained therein by locking means 5 such as mortar or plugs or any other suitable (lOVlCQ. For

the operatiaru of my reintorccuumt it is necessary that the ribs 4. be securcl y locked in the. recess 2.

In Fig. Z'the ribs 4- and. the plates 3 are channeled indicated for the reception of Those plates are pro-' the reinforcing element 6 which consists of a flat .curvcd plate, which elements are inserted. as shown. at intervals between the plates 3 anrl the blocks L Fig. 3' shows clearly the channelin In Fig. at, the construction is the same as in Fig. 1, except that the locking means 7 for retaining the ribs 'il-ln the recess 2 are strengthened, by reinforcing members 8 preferably in the form of metallic rods 01- bars 8 for the purpose of longitudinal reinforcement.

' In sewer construction. ordinary pressures or strains will be withstood but if the sewer is 'to-be subjected to abnormal strains, reinforcing is required. Dependent upon conditions, sometimes longitudinal reinforcing-is required, sometimes transverse reinforcing, and sometimes both. Considering transverse reinforcement first, the reinforcing clearly must be inserted l'ietween the lining plates 3 .nnl the outer block 1 in order to be most elle tive. 'Tnorder to so place the reinforcing elements, the ribs at and theplates have to be'channclcd to permit their inscrtion. The reinforcing is to sustain downward pressure upon the sewer section. .lt' the reinforcing; elements were simply placed between two layers of bricks or blocks, when the excessive downward pressure came, it would tend to straighten out the reinforcing element which in turnv would force the lower layer of blocks :part from the upper layer and thereby causing a rupture unless the lower and upper layer of blocks are securely locked together so that the insertion of the reinforcingelement is useless unless the two layers of blocks are secured together. This requisite locking together of-the upper and lower blocks is secured by the structure shown in Fig. .l.

Considering the longitudinal reinforcement, this is best secured by placing it just above-the transverse reinforcing so I place it Within the locking members 7. This is not only a convenient and ellicieut location for it but by adding stillness to the mombcrs 7 it adds to the effectiveness of the looking members 7 in retaining the ribs 4: in the recess 2.
